43.1 Definition

Stream iterators are used to access an existing input or output stream using iterators. In the C++ standard, the template classes istream_iterator and ostream_iterator are referred to as the stream iterators. istream_iterator reads successive elements from the stream for which it was constructed using the extraction operator>>(); ostream_iterator writes values to its respective stream using the insertion operator<<().

The class templates istreambuf_iterator and ostreambuf_iterator are used to extract and insert individual characters from stream buffers.
